Abstract: Currently operating tools with deep-sea manned submersible sampling become a trend,through the analysis of the Jiaolong manipulator and manned submersible device with different tools,design a new deep-sea mineral cutting sampling equipment.The manipulator and carry knives cutting sampling system are analyzed in the workspace and trajectory by MATLAB,compare whether pick up tools work space change,and through the ADAMS to analysis the stress of several different mechanical operating posture,has a guiding role to the positioning of the bottom of the submersible and the operation posture of the manipulator's in cutting operation.

Key words: Jiaolong manipulator, cutting and sampling system, working space, operating posture
